HEADLIGHT.

Specification of Letters Patent.

Patented Mar. i0, 1918.

Application filed July 13, 1916. Serial No. 109,015.

.cially adapted for. automobiles and other vehicles, and'has for itsobject to provide a simple and eiiicient means for keeping in vproperadjustment, light bulbs which either have two lam'ents whichshould besetverticallyl or which have a'single diametrically extended filament thatshould be .set verti-.` cally, or for that "matter, in anycer'tainposition, in respect to a vertical, necessary in order to getthe best or desired results.

The feature of the resent invention'consists in combining a light bulbof the above character with a reflector that is capable 'of rotary oroscillatory adjustments with the light bulb', to set its filament eithervertically or in predetermined positions, in respect to a vertical. v

In the accompanying drawings which illustratethe invention, likecharacters indicate-like parts throughout the several views.

Referring tothe drawings:

Figure 1 is a front elevation showing the improved reiector; and

Fig. 2 is av vertical section takenon the line w2-2 of Fig. 1, theclamping rim of the headlight-'being removed.

The case 3 of the headlight has a 'rigidly .secured angular facing rim4. The clamping rim 5 which holds the lens or glass plate 6, may be ofthe usual or any suitable construction detachably secured to the rim ofthe casing, by the customary joints or other suitable devices. Thereiiector 7, which, as stated, is mounted for rotary adjustments withinthe casing, is formed with a rim portion 8 held between the rims 4 and5.

Springs 9, .as shown,.threein number, are interposed between therims 4and 8 and yieldingly press the latter forward. These sprin as shown, areI nade from piecesof bowe spring wire having their ends 1nserted throughperforations in the rim 4.

The rim 8 is provided with segmental slots 10, as shown, three innumber, and adjacent to the edges of these slots, said rim is formedwith serrated surfaces 11. These serrated surfaces 1 1 are engaged bythe V-shaped edges of the angular heads 12 of studs 13 that are riveted,soldered, or otherwise rigidly secured to the rim 4 and 'are extendedthroughthe cooperating slots 10. At one extremity, the slots 10'areprovided with ltransversely enlarged passages 10a through which theheads12 may be freely passed,

when alinedtherewith by extreme rotationl of the reflector in onedirection.

Under the tension of the. springs 9, the ser.

rated surfaces 11v willbe held engaged with the angular heads 12 withsuiiicient 'force to prevent accidental rotation ofthe reflector, butnevertheless, the said 'reflector may be easily rotated 'when it is'pressed lslightly rearward and then given a turning force'by the use ofva persons hands.

The electric light bulb 14, as shown, is ofA thetwo-ilament type, beingprovided with an axial filament a and an offset filament b, and t-isprovided on its shank with the customary metallic contact sleeve' 15'having idiametrically projected lock lugs 16 -Thesleeve'l is insertibleinto and closely lits a sleeve-like socket 17 that is secured in thelrearwardly projected sleeve-like axial hub 18 of thereector 7. The locklugs 16 are adapted to be engaged with bayonet slots 19 formed inthesocket 17 and to be held l interlocked therewith by the tension of acoiled spring 20v compressed between the shank of the bulb and aninsulating plug 21 secured inthe rear end ofthe socket 17 and serves tosupport certain of the electrical connectionsto the light bulb. These.electrieal connections need not here be considere It is evident thatwhen the bulbis applied to the socket, and hence, is secured in respect4to the reflector, its filament orlaments may not always stand in avertical plane, but that they may be accurately set in a vertical planeby rotary adjustments of the reiiector within lthe casin What claim is:

1. In a headli ht, the combination with a reiector mounted for rotaryadjustments, of an electric light bulb mounted therein and partaking ofa common rotary adjustment therewith, and means for holding said re-Hector against accidental rotation, comprising a serrated surface ononeof said parts, and a coperating head onthe other of said vparts,4 thesaid head and serrations being spring-held in contact.

2. n a headlight, the combination With a casing, of a reliectorrotatably mounted 5 therein and provided with a marginal rim havingsegmental slots and serrations adjacentto said slots, studs applied tosaid casing and Working through said slots and provided with headsengaging said Serrations,

10 and springs interposed between said casing and the rim of saidreector for yieldingly holding said serrations and coperatlng heads incontact.

In testimony whereof I affix my signature in presence of two witnesses.
